i i This invention pertains to. clothes wringcrs, andmore particularly to wringers employed in connection with power-driven washing machines.-

The invention has primarily for itsobject. to

6 v provide an exceedingly simple; and inexpensive power-driven wringer, capable of positive pressure control and quick release.

t Another object resides in. the provision of a wringer having rolls, normally positioned at an 10 angle to the vertical axis of themachine, thus materially facilitating inspection and handling of material passing through the rolls, from the feeding position of the operator at the rear of the wringer;

6,. Another object of the invention resides, in the provision of a quickly releasable and; detachable pressure roll, which permits ready access ta the material in the event the same becomes entangled in either the pressure or'driven roll.

A still further object resides in the provision of a novel feed trough designed to allow ready feeding of the material to the rolls, either by hand, or with a stick or paddle,v and at the same time prevent contact of the hand or fingers'with':

26 the rolls.

Incidental to the foregoing,a more specific:

object of the present invention is to provide a clothes wringer in which the pressure roll is carried by a quickly detachable shiftableframe 30 frictionally locked in pressure adjusted position, and both automatically and manually releasable upon creation of excessive pressure, or jamming of the rolls.

With the above and other objects in- View, which will appear as the; description proceeds, the

invention resides in the novel construction, combination, and arrangement of parts, substantially ashereinafter described, and more ticularly defined by the appended claims,-it be- 0 ing understood that such changes in the precise embodiment of the herein disclosed invene, tion may be madeas come within the scopeof the claims. .c I

In the accompanying drawingsis illustrated *5 one complete example of the physical embodi ment of the present invention constructed ac cording to the best mode'so far devised for the practical application of the principles thereof, In the drawings: 1 so.

Figure 5 is. a detail section taken on the line 5-5 of Figure 2.

Referring now more particularly to; the accompanying drawings, the numeral I designates, a base bracket provided with vertical end plates 2, in which the shaft 3 of the driven roll 4 is suit- 0 ably journaled. The base bracket it, attached to the usual transmission housing 5, with which conventional power-driven washing machines are equipped;

Mounted upon the base bracket I, is an inverted U-shaped frame designated generally by the numeral 6, and comprising a transverse tubular head 1, provided at its ends with depending arms 8, the lower ends of which are bifurcated at 9: to straddle the shaft 3 of the driven roll 4, 29 as. best shown'in: Figures. 1 and 2, thus permitting both oscillatory and radial shifting movement of the frame 6- with relation to the axis of the driven roll 4.

The upper edges M; of the end plates, 2 are arcuate' in shape with relation to the axis of the driven shaft 3, and formed uponthe inner faces of the plates adjacent their front and rear ends are cams H, which are engaged by idler rolls l2 carried by the arms, 8; of the inverted U-shaped 39 frame 6, thus causing the frame to be shiftedradially with relation to the axis of the driven roll. 4 upon oscillation of the same either manually or automatically, as will be hereinafter described An idler pressure roll I3 is journaied 35,

in the arms8', and in operative, position normallyengages the driven roll 4, the pressure between thegrolls, being determined by the position by means of a frictional clutch l4 carried by the frame 5, and comprising a manipulating handle l5 -rotatably mounted upon the tubular head 1, and connect d to. oppositely extending rocker arms IS, the ends of which are: secured to. the cam heads I1, which carry the headedstuds i3.

*journaled in the depending arms 8, as best shown in Figures 2, 3, and 4." The contacting faces between the arms 3 and the cams I! are such as to transversely shift the studs l8 upon rotation of the cam heads I! by manipulation of the handle I5, thus causing the sides of the end plates 2 and the cams l l to be frictionally gripped between the heads of the studs and the arms 8,

which locks the frame 6 in adjusted position.

over and seat themselves in the saddles I9 carried by the end plates 2, and cause the pressure roll l3 to be shifted away from the driven roll 4. 'As best shown in Figures 1 and 2, a rocker plate 26, conforming in con'tour to one of the saddles I9, is fast to a stud 20 journaled in one of the end plates 2. Secured upon one of the studs is a depending arm 2| provided with a laterally projecting plate 22 having a cam slot 23 formed therein for reception of a roller 24, fast on the shaft 25 for controlling the transmission housed in the casing 5. In vertical inoperative position 1 of the frame 6 the roller is in a central position with relation'to' the cam slot23, which throws the transmission into neutral,- and upon oscillation of the frame in either direction, the

roller l2 will engage resilient fingers 26f carriedv by theplate' 26 to rock the arm 2|, and shift the transmission bar25 to drive the roller 3 in the desired'direction with relation to the position of the frame 6. I

While a specific type of friction clutch and transmission control has been illustrated. and

described, it is understood thatvarious arrangements are contemplated within the scope of the' present invention, the salient feature of. which resides in the oscillatory and shifting movement 2: of the pressure roll carrying frame to effect quick release of the rolls, and positively determine the pressure betweenthe same. a i

In the operation of the present invention, as

suming the rolls to be in their inoperative posi-' tion, as shown in the drawings, to throw the same into operation it is merely necessary to manually shift the frame 6, which causes the rollers l2 to ride off of the saddles l9 and radially shift'the frame 6 with relation to the axis of the driven roll 4, causing the pressure roll to engage the driven roll. The pressure between the rolls is then determined by the position of the frame 6 with relation to the cams I l and when the desired pressure is effected, the frame is locked in its adjusted position through manipulation of the'handle I5, which actuates the clutch M to frictionally bind the frame upon the end plates 2. Obviously, oscillation of the frame 6 alsoefiects rotation of the rocker plate 26 to throw the driving transmission into operative engagement with the driven roll, in the manner heretofore described. H

In the event it is desired to release the rolls, a

slight rotation of the handle l releases the clutch l4, and the frame is then free to oscillate toward the saddles l9, and at the same time shift radially as they rollers ride up upon the saddle to space the rollers and throw the transmission into neutral, which renders the wringer inoperative.

In addition to manual release of the wringer, should articles become jammed or stuck within the rolls, creating excessive pressure, or tending to stop their rotation, the force created would be sufficient to overcome the frictional bind between the end plates 2 and the frame 6, and cause the frame to be shifted toward its vertical position, due to the direction of drive of the roll 4, which would automatically space therolls and release the material caught therebetween, as well as causingthe driving transmission to be thrown into neutral.

1 In addition to the foregoing, should articles become wound upon either of the rolls, the entire frame can be readily removed from the base bracket bymerely lifting the same upwardly.

The foregoing is accomplished by means of a trough provided with a transverse rib 21 detachably mounted upon the studs 29 carried by the end plate 2, and supported by legs 30 engaging the edges of the base bracket. "I'he'trough 21 is provided with a transverse rib. 3|, and terminates in an upturned inner lip 32 adjacent the driven roll 4. Positioned above the rib 3 I, and journaled in the sides'33 of the trough, is a guard 34, preferably in "the form of an idler-roll. Obviously, the guard 34, in cooperation .withthe' rib 3|, forms a restriction to prevent insertion of the hand suffi ciently to allow contact of the fingers with the rolls, and yet atthe same time allow feeding of the material to the rolls. The bottom of the trough between the rib 3i andthe inner lip 32 is provided with a transverse-series of openings 34 to allow drainage. From the foregoing explanation, considered in novel structure of wring'er has" been devised, which not only allows rapidadjustment and release of the pressure roll, but also quick detachability and complete access to material entangled in the rolls.- In addition to the foregoing, due to the angle at which the rolls are set in operative position, the operator has full vision and access to material fed to the rolls from the feeding position, whereas heretofore it has been necessary for the operator to stand at the side of conventional wringers.
